We haven't even had coffee yet, but leave it to Rihanna to give us a better Monday wake up call than any amount of Starbucks ever could. The singer shot a brand-new ad campaign this weekend (!!!) and posted the photo above to Instagram for proof, leaving any remnants of early morning sleepy eyes and snooze button drowsiness far, far behind us. She looks gorgeous, with a full face of makeup (smoky eyes, red lips, perfect hair, CHECK!) and clad in only a white towel, save for some Chanel baubles on her neck. But wait...what's the photoshoot for?! THAT'S the real question. Rihanna's been a total lady of mystery these past few weeks, between other covert photoshoots with Terry Richardson and big fashion bombs like the announcement of her London Fashion Week debut. Now she's teasing us yet again, tweeting "And that's a #wrap on my shoot for my new #topsecret [sic] add campaign!!! #2013 #phuckyobasic." Hm...let's break down the clues, shall we?

For one, it MUST be noted that RiRi's sporting her pixie cut in the ad, not the longer locks she's been working lately. So this means she's either reverted back to her chic crop OR the photo was taken a while ago and she's only posting it on Instagram now. Another hint: she's dripping in Chanel jewelry, which leads us to believe that she's shooting for the French fashion house. But is that too obvious? Rihanna's been a major fan of the brand since wayyy back, and considering all the style cred she received for those vintage pearl Chanel shades from the Victoria's Secret Fashion Show, this would make TOTAL sense. Not to mention, the pop star's beauty look has the same Old Hollywood glamour that Chanel is known for. Given her bold red lipstick and pitch perfect sultry eye makeup, our money's on a beauty campaign. What do you think? Place your bets below....
